Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a storage phosphor sheet holder containing a storage phosphor sheet, for example, in a light-shielded dark room in a radiation image information reading apparatus. Automatic transfer, the holder is automatically opened, the stimulable phosphor sheet in the holder is naturally dropped by its own weight, transferred to the outside of the dark room, and conveyed to, for example, a reading unit of the reading device. The present invention relates to an automatic insertion mechanism for a stimulable phosphor sheet.

<Prior Art> Recently, a radiation image information recording / reproducing system using a stimulable phosphor has attracted attention.

Here, the stimulable phosphor refers to radiation (X-ray, α-ray, β-ray,
Ray, γ-ray, electron beam, ultraviolet ray, etc.), accumulates a part of the radiation energy, and then, when irradiated with excitation light such as visible light, radiates according to the accumulated energy. A phosphor that emits light.

The radiation image information recording / reproducing system utilizes the stimulable phosphor, and emits radiation emitted from a subject or transmitted through a subject, on a sheet having a layer made of a stimulable phosphor (hereinafter referred to as a stimulable phosphor). The stimulable phosphor sheet is scanned once with excitation light such as a laser to generate stimulated emission light, and the resulting stimulated emission light is photoelectrically read to obtain an image signal. After getting,
Based on this image signal, a radiation image of the subject or the subject is output as a visible image on a recording material such as a photographic photosensitive material or a CRT.

The stimulable phosphor sheet is also referred to as a radiation image conversion panel, and is usually a sheet having a shape such as a rectangle or a square (each side of which is about 20 to 50 cm). And a phosphor layer provided on the substrate. In general, a transparent protective film made of a polymer substance is provided on the surface of the phosphor layer to protect the phosphor layer from chemical alteration or physical impact.

The above-mentioned radiation image information recording / reproducing system uses the conventional X
1) Organisms, biological tissues, and biological images can be obtained because radiographic images can be obtained with much lower radiation exposure doses than radiographic methods using X-ray films. By detecting one-dimensional and two-dimensional positional information of a radiolabeled substance contained in a sample such as a medium containing a substance derived from a tissue and / or an organism (hereinafter, simply referred to as an organism sample), for example, For studying metabolism, absorption, and excretion pathways and conditions of administered substances, and for studying genetic information in living organisms, and 2) X-ray photography for medical diagnosis of the human body Is very advantageously used in direct medical radiography and the like.

In the radiation image information recording / reproducing system, the stimulable phosphor sheet is not for finally recording the image information, but temporarily holds the radiation image information for giving an image to the recording medium as described above. The radiation energy remaining in the stimulable phosphor sheet after the reading is performed by the irradiation of the excitation light is released by the irradiation of the light to erase the remaining radiation image, and the stimulable phosphor sheet is erased. It is extremely economical and convenient to use body sheets repeatedly.

The radiation image information recording / reproducing system is disclosed in, for example, JP-A-55-12429, JP-A-56-11395, and JP-A-55-163472.
JP-A-56-104645 and JP-A-55-116340, and the application of the system to autoradiography is disclosed in JP-A-59-83057 and JP-A-60-10174. ing.

In the above-mentioned radiation image information recording / reproducing system, the stimulable phosphor sheet for accumulating and recording the radiation image information is read before and after photographing in radiation imaging or before and after contact exposure in autoradiography and for reading the accumulated and recorded radiation image information. Before this, they must be kept in a dark place, protected from light. This is because an excitation light component (a component that causes photostimulated luminescence) contained in natural light, room light, and the like, and an ultraviolet component that generates noise energy are stored in the stimulable phosphor sheet. This is because a part is emitted or accumulated and recorded as noise. Therefore, strict care must be taken when handling the stimulable phosphor sheet after radiography or after contact exposure, for example, in a dark place. In order to improve handling, the sheet is stored in a cassette, holder or magazine, etc. It is generally handled in a state.

By the way, in autoradiography, a subject containing a radioactively labeled substance is exposed to a stimulable phosphor sheet in close contact exposure, and image information such as positional information of the radioactively labeled substance is accumulated and recorded. Is stored in a light-shielding stimulable phosphor sheet holder in a dark place, carried to the radiation image information reading apparatus while being stored in the holder, and read. In the apparatus, it is taken out of the holder and set on the reading device.

<Problems to be Solved by the Invention> By the way, the stimulable phosphor sheet on which the radiation image information is accumulated and stored is stored in the stimulable phosphor sheet holder, carried to the radiation image information reading apparatus, taken out from the holder, and It is not easy to set the stimulable phosphor sheet in the reading device. Therefore, the stimulable phosphor sheet is set in the reading device while being stored in the holder, and the holder is automatically opened in the device to take out the sheet.
